我是否知道是否需要启用Multi-Dex? (ClassNotFoundException) [英] Do I know if I need Multi-Dex enabled? (ClassNotFoundException)

问题描述

突然，似乎根本没有任何原因，以下错误开始出现.经过一整天的努力，我发现启用Multi-Dex可以解决该问题.此错误是否可能是由于我违反了64k参考阈值?

Suddenly and seemingly for no reason at all, the following error starts presenting itself. After fighting it all day, I discovered enabling Multi-Dex resolved it. Is this error potentially caused by my breaching the 64k reference threshold?

java.lang.RuntimeException: Unable to instantiate application md52323d240c954a07dbdbeb3f1c41a0cab.MainApplication: java.lang.ClassNotFoundException: Didn't find class "md52323d240c954a07dbdbeb3f1c41a0cab.MainApplication" on path: DexPathList[[zip file "/data/app/com.myapp-1/base.apk"],nativeLibraryDirectories=[/data/app/com.myapp-1/lib/arm64, /data/app/com.myapp-1/base.apk!/lib/arm64-v8a, /system/lib64, /vendor/lib64]]

我可以在哪里看到引用计数?我怎么知道是否超过了-特别是在VS中?

Somewhere I can see the count of references? How do I know if I surpassed this - in VS specifically?
